Help with Alarms API

[API_User]

Hi,
I'd like to check a few things regarding the Alarms API.

How are we supposed to treat the Severity being return by the API?

With severity levels of Low, High, Warning, Urgent (and possibly more?), what are we supposed to interpret from these values?
What is the difference between the levels?
At which level(s) must immediate action be taken?


How can we map the different alarm types and classifications, to the Electrical/Mechanical Alarms guide provided?

We'd like to link up the different active alarms that we get from the API reply to the different categories in our application to indicate the severity of the different categories of assets in our datacenter
